Trains collide in Chicago, 12 minor injuries

CHICAGO (Reuters) - An Amtrak train and a Metra commuter train collided at Chicago's Union Station on Friday, resulting in up to 12 minor injuries, officials said.

The Amtrak train was leaving the station when it collided with a Metra train entering the station from the south suburbs in the city's downtown, according to Metra spokesman Tom Miller. As many as six Metra cars were damaged, Miller said.

Both trains were traveling at a slow speed when the accident happened at about 8:30 a.m. local time, Miller said. A Chicago police spokesman said the trains possibly sideswiped each other.

Trains could not enter or leave the south side of the station for about an hour and a half after the accident.
